Description
Gain Up to 35HP. If you have a blown or modified setup in your New Edge Mustang, upgrading to a Granatelli Coil-on-Plug kit will deliver the spark your Pony needs to get the most from your mods. Your weak OEM coils don't deliver a strong enough spark to your plugs to ensure you're getting the most power possible from your engine, especially once you've added high performance parts. This kit adds up to 15HP on naturally aspirated Mustangs and an impressive 35HP on turbo or supercharger setups.

Up to 400% More Voltage. Your stock coils deliver 20,000 volts, versus the GMS coils which are rated at 60,000 volts. And this kit features a no-resistance connector cable design so all of that voltage is being delivered where it counts.

Complete Kit. This complete kit includes all hardware necessary for installation including the 8 coil packs, connector cables, and stainless snap lock plug connectors.

Easy Installation. Upgrading your coils is easy with this kit, which is OBD-II safe and a direct replacement for your OEM setup. You'll enjoy more power, improved throttle response, and even better fuel economy with an hour or less install time using basic hand tools from this GMS Coil Plug Kit.

Application. The Granatelli Coil-on-plug upgrade kit is designed for 1999-2004 SVT Cobra & MACH1 Mustangs.

    GMS 4V Pro-Series Coil Pack

    The coil pack worked great the first 1500 miles great gain in hp after 1500mi the coil pack burned one at a time after the third coil pack burned out i just pulled them all out now i haft to put my stock coil packs back in and i'm out 500.00 i wouldn't recommend anyone tobuy these coil packs you will be buying trouble; furthermore, if you continue to drive on cylinder misfire due to a burnt out coil pack it will only lead to more problems and other parts to replace.

    • Response from AmericanMuscle

      I am very sorry to hear your coil pack failed after such a short period of time. I suggest that you contact GMS directly at 805-486-6644 as they do have a 90-day warranty on the majority of their performance parts and they may be able to assist you with this issue.
